SQL SERVER 还原数据库名称不同的备份

string fileName = "";//备份路径文件名
string DBName = "";//备份数据库名
string LogName = "";//备份数据库日志名
string fileDataBase = "";//数据库路径文件名
string fileLog = "";//数据库日志路径文件名
//获取备份文件中数据库逻辑名
sql = string.Format("RESTORE FILELISTONLY FROM DISK= '{0}'", fileName);
using (IDataReader dr = BaseClass.GetDataReader(sql, BaseClass.connectionBase))
{
if (dr.Read())
{
do
{
if (dr.GetValue(6).ToString() == "1")
DBName = dr.GetString(0);
else if (dr.GetValue(6).ToString() == "2")
LogName = dr.GetString(0);
} while (dr.Read());
}
}
//获取当前帐套数据库及日志路径文件名
fileDataBase = BaseClass.ExecuteScalar("select filename from sysfiles where fileid = 1 ", BaseClass.connectionPrivate).ToString();
fileLog = BaseClass.ExecuteScalar("select filename from sysfiles where fileid = 2 ", BaseClass.connectionPrivate).ToString();
//构建还原SQL
sql = string.Format("RESTORE DATABASE [{0}] FROM  DISK = N'{1}' WITH  FILE = 1,  MOVE N'{2}' TO '{3}',  MOVE N'{4}' TO N'{5}',  NOUNLOAD,  REPLACE,  STATS = 10", BaseClass.currAct, fileName, DBName, fileDataBase, LogName, fileLog);
